Study summary

For many patients with hematologic disorders and bone marrow failure, hematopoietic stem cell transplantation (HSCT) or cellular therapy (CART) offers a curative treatment option. Patients after SCT or CART have a variable period of immune deficiency in the post-treatment period. The response to vaccination may affect the outcome of the transplant patients. the immunogenicity of vaccines in this immunosuppressed population is uncertain and variable. HSCT and CAR-T recipients are in a COVID-19 high-risk group and conferring immunity by vaccination at the earliest effective timepoint is desirable. At present, the immunogenicity and efficacy of SARS-CoV-2 vaccines in immune-impaired patients including autologous and allogeneic HSCT recipients is unknown. Furthermore, the impact of GvHD and IST on SARS-CoV-2 vaccine immunogenicity is unknown. the investigators aim to evaluate the vaccination response to COVID vaccines after SCT and CART

Read the detailed description

so for participants with SCT or CART who decide to get their vaccines, the investigators will measure response by therapy by measuring COVID-19 serology IgG at the following schedule: Baseline +5 days after vaccination; 1 month +/- 10 days (after the first dose), 2 months +/- 10 days (after the 2nd dose), 3 months +/- 10 days, 6 months +/- 10 days and 12 months +/- 10 days In addition, also the investigators will collect CD4 and Total IgG which is the standard of care of these patients post SCT and CART

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2021 to primary completion in Dec 2023, 32 months.

Of 47 non-industry observational studies under Hematologic Diseases, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 190. This study's 32 months is below that.

Counting every sponsor, half of 64 studies reached it within 51 months; a quarter within 16 and three quarters within 78.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 23, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
